This may seem unrelated at first, but see:
There are still people around who bought there BBs as productivitiy tools (like myself). They are willing to learn how to use the tool but they expect that it works. They are not willing to invest tons of time to become experts themselves - although they might, like me, a professor of informatics. If things don't work people like me just want advice. If they rather feel like being a target of education they make react irrationally - like the post that I'm responding to - or rationally - move on to a different vendor. To conclude: I would also be happy about a more appreciating style of those in the know. Thank you
